I would be interested to see all the steel types ranked by total surface area within the polygon.

I went through manually and these appear to have the highest volumes:

H1

H2

CPM Magnacut

Sandvik 12C27

Interestingly they are all weak on Edge Retention.

The data this site is using really seems questionable.
